    signals: mv {dis,}allow_signal() from sched.h/exit.c to signal.[ch] · 0341729b
    Oleg Nesterov 提交于
    Move the declaration/definition of allow_signal/disallow_signal to
    signal.h/signal.c.  The new place is more logical and allows to use the
    static helpers in signal.c (see the next changes).
    
    While at it, make them return void and remove the valid_signal() check.
    Nobody checks the returned value, and in-kernel users must not pass the
    wrong signal number.
